 Description   

obdfilter-survey test 2a (netdisk) runs something like "lctl test_brw 30 wx q 256 4t3 g". In jt_obd_test_brw() we expect an integer after the 'g':

                        case 'g': /* plug and unplug */
                                data.ioc_pbuf1 = (void *)2;
                                data.ioc_plen1 = strtoull(argv[6] + 1, &end,
                                                          0);
                                break;

Since there isn't one, ioc_plen1 is zero and obd_ioctl_pack() returns -EINVAL and OBD_IOC_BRW_WRITE isn't actually called.
